Compiler Warning (level 1) C4047

'identifier1' : 'operator' : different levels of indirection from 'identifier2'

A pointer can point to a variable (one level of indirection), to another pointer that points to a variable (two levels of indirection), and so on.

Example

void main() {
    char **p;// two levels of indirection
    char *q; // one level of indirection
    p = q;   // warning C4047
}
